Question

Evaluate (102) using suitable identity.​

Answer 1

Using identity, answer is 1061208

Step-by-step explanation :

( 102 )³

It can be written as ;

( 100 + 2 )³

Using identity here ;

( a + b )³ = a³ + b³ + 3ab ( a + b )

⇒ ( 100 + 2 )³

⇒ (100)³ + (2)³ + 3 * 100 * 2 ( 100 + 2 )

⇒ 1000000 + 8 + 600 ( 102 )

⇒ 1000000 + 8 + 61200

⇒ 1061208

Hence, the required answer is 1061208
